Abstract
Unlike the other disubstituted naphthalene derivatives, peri-substituted naphthalenes cannot be synthesized by Friedel-Crafts condensation. Duswalt and Mayer3” prepared 13 of the 14 possible ethylmethylnaphthalenes by alkylating 1-and 2-methylnaphthalene. Sterically hindered 1-ethyl-8-methylnaphthalene was not found among the products. We did not anticipate that the preparation of 7 and 12 should present unusual synthesis problems ...
